January is the peak month for cyclogenesis in the western Gulf of Mexico (Saucier, 1949), and under these conditions, Frontal Overrunning weather spreads across much of Texas and southwestern Louisiana.
The occurrence and diurnal pattern associated with Frontal Overrunning weather during January at Lake Charles is primarily associated with cyclogenesis in the western Gulf of Mexico.
Many GALE researchers say they came into the program with the suspicion that the ocean plays a more important role in cyclogenesis than most models assumed.
Some researchers argue, for example, that the Appalachian Mountains, which reach their tallest height in western North Carolina, help to focus cyclogenesis along the coast by redirecting airflow.
And at even higher altitudes of about 25,000 to 40,000 feet is the jet stream, another element thought to be important in cyclogenesis.
As anticipated by some, this tropopause fold seems to be a very common event when cyclogenesis processes are occurring,' says Smith.
